4.    Income Taxes

U.S. Cellular is included in a consolidated federal income tax return and in certain state income tax returns with other members of the TDS consolidated group.  For financial statement purposes, U.S. Cellular and its subsidiaries compute their income tax expense as if they comprised a separate affiliated group and were not included in the TDS consolidated group.

U.S. Cellular’s overall effective tax rate on Income (loss) before income taxes for the three and nine months ended September 30, 2015 were 38.5% and 39.2%, respectively.  The effective tax rates for the three and nine months ended September 30, 2014 were not meaningful due to the relatively low amount of Income (loss) before income taxes and the impact of a $6.4 million tax expense related to a valuation allowance recorded against certain state deferred tax assets.  U.S. Cellular determined that such deferred tax assets were not realizable, on a more likely than not basis.
